450 t Four-Girder Casting Crane for Electric-Furnace Steelmaking
A 450 t casting crane uses a four-girder, four-rail structure and integrated safety monitoring for molten-metal handling.
The project and its handling task.
The 450 t crane was customized for an electric-furnace steelmaking application. Its main duty is transporting molten metal, where the ladle, below-hook gear, travel route and operating sequence must be treated as one lifting system.
A four-girder, four-rail arrangement supports the heavy-duty structure. The trolley frame is annealed and machined as a complete assembly to improve assembly accuracy. Finite-element analysis was used to coordinate the structural and mechanical design.
Plan the heavy molten-metal lift around the actual furnace route.
Very heavy ladle movements need more than a nominal capacity: runway loads, heat, stopping behavior and crane redundancy all affect the melt-shop design.
Calculate the filled ladle, beam and hook load for each refining move.
Check furnace, transfer and pouring positions against span and hook coverage.
Verify travel, monitoring, braking and emergency operation with the project lift plan.

Custom equipment application.
The project applies a purpose-designed casting crane to molten-metal transfer. PLC control and a safety-monitoring management system support operating supervision and maintenance records.
For a similar project, set the 450 t casting crane within a four-girder, four-rail handling plan. Define the filled ladle and rigging, hook approach, route clearances, controls and emergency actions before freezing the steelwork or runway.
Continue from the project to the right crane family.
Use the project as a reference and specify the crane against your own yard layout and cargo.

Questions before specifying a similar crane.
Can the same project crane be supplied for my site?
We customize the capacity, span, lifting height, attachment and controls to the load, building or yard layout and operating cycle. Filled ladle and rigging mass is one of the inputs to review before final equipment selection.
How are certification, quantity and lead time agreed?
Single-crane and fleet enquiries are welcome. Define the destination and required standards in the enquiry. The project offer confirms certification and inspection documents, the quantity, drawing approval and manufacturing schedule, with the shipping and site-service boundaries.
What should acceptance and after-sales support include?
Agree the inspection plan, representative load and functional tests, operator training, maintenance instructions, spare-parts scope and fault-recovery procedures. For this application, include applicable safety and monitoring requirements in the technical review.
